i.e., the first time \(t\)  that the sum of the weights of the force points which collide with \(W\)  at time \(t\)  is at most \(-2\) . The continuity of the \(\mathrm {SLE}_\kappa (\rho )\)  processes (with a single force point) with \(\rho < -2\)  was proved in [1]}, [2]}. When they are not interacting with their force points, \(\mathrm {SLE}_\kappa (\underline{\rho })\)  processes locally look like ordinary \(\mathrm {SLE}_\kappa \)  processes and in this case can be obtained by weighting the law of an ordinary \(\mathrm {SLE}_\kappa \)  by a certain martingale; see [3]}. For more on \(\mathrm {SLE}_\kappa (\underline{\rho })\)  processes see [4]}.
